Group, anyone have experience with installing a MFJ 1777 Doublet Antenna?
How was it installed? What issues did you encounter? Thanks!

Hi Norm, I have never installed an MFJ 1777, but have installed dozens
of antennas just like it. The antenna is a 102' doublet fed with 450
ohm ladder line. The MFJ manual says it has to be used with a balanced
antenna tuner. A new or used balanced antenna tuner will cost 3-4
times the $50 price tag for the antenna. The antenna will have to be
used with some type of tuner, a "T" type will work, or a simple "L"
network, with a suitable balun.
As far as installing, hang it high enough so the transmission line
just gets to the tuner, that would be optimum.
If you want to use it on 160M that will require reconfiguring the
antenna, not that difficult, but still a pain.

Thank you Gary. If you think of anything else, let me know.
